Abstract

Currently the demand for materials, including polymer composition materials is dynamically increasing.Tendencies in assessing of current and alternative opportunities are being observed in the researches on providing relevant demand. One of these tendencies, i.e. the urgency of the researches carried out for use of biomass residues as a component of polymer composition materials should be mentioned.    Investigations of primary sources indicate the existence of the research data of biomass residues as a component of polymer compositions from the 70-s of the last century. The present study provides information on the study of the content of new composition materials with the addition of biomass based on the exploited low-density polyethylene. In this process, such factors  as the effect of biomass  added to the polymer matrix on the biological activity of the composition, the application directions of the composite products, the management of the biodegradation period of the corresponding waste and etc. are analyzed.  Comprehensive assessment of the factors as change of biological activity – biodestructive resistance in a wide range of compositions corresponding to various substances in the content  of the used biomasses, their impact on the composition of the relevant indicators and etc. is expedient. At the same time, it is important to take into account the aging rate of LDPE - the formation of gel- and zol-fraction, structural and chemical transformations. The use of LDPE wastes, which have a higher mass than polymer waste and biomass residues increases the scientific-practical, mainly environmental and economic importance of the research..
